Biesel, and a group of engineers at the Laboratoire Dauphinois d'Hydralique (Neyrpic).This comp11ation comprises four articles dealing with tile design and characteristics of wave-generating machinery. Part I, which is composed of the first three articles, defines the problems incidental to wave-generator operation and evaluates many machines currently in use. It also presents a theoretical analysis of wave generators, the results of which describe the wave generated and the forces acting upon the wave machine. In Part II a group of engineers at the Dauphin Hydraulic Laboratory (Neyrpic) relate in detail how they have managed to meet the design and motion requirements of laboratory wave generators. By way of illustration the authors describe three different laboratory installations for the study of waves or harbor problems. In conclusion, they indicate the necessary and feasible improvements in design and construction of wave-generating machines; most of these improvements have already been incorporated in prototypes and tested.en-USReport
